5 Claims.

This invention relates to fastening devices,

especially to looks, and more particularly to a proved hasp-lockfastening devices for use as standard equipment upon aseries of cabinetsinstalled along the right-of-way of a railroad and intended forcontaining operating relays, tools and supplies, etc.

It isdesi-rablethat such cabinets be secured against accessto theirinterior by unauthorized persons, but readily accessible to numerous individual operatives each provided with a master key adapted to lockandunlock. all the padlocks by which term the fastening devices for suchcabinets are known generally to such operators, whether or not theyinclude aconventional padlock orany suitable locking device not operableby hand without some form of key or actuating member.

Other objects and advantages will appear as the" description" of" theparticular physical. embodiment selected to illustrate the inventionprogresses, and the, novel features will be particularly pointed out inthe appended claims.-

In describing the invention in detail and the particularphysical-embodiment selected to illustratetheinvention, reference willbe had to the accompanying drawing and the several views thereon; inwhich like characters of reference designate like parts throughout; theseveral views, andtin which:

Figure 1 is a view in horizontal section of a hasp-lock fasteningdeviee',1in the construction of which the invention has been" embodied,and shown in position upon the associated parts of a cabinet to whichitis applied including portions of the door-frameandswinging door; Fig. 2is a front elevational view of the device as shown by Fig; 1, with someparts broken away to more clearly show the construction; Fig. 3 is aView inside elevation'of the device shown" in Figs. 1 and r 2; Fig; 41sa detail view like Fig. 3, but showing the keeper member separately;Fig. 5- is a plan view of the mounting pivot memberfor the hasp, takenseparately; Fig. 6 is a fragmentary, detail view like Fig. 1, butshowing a modification.

Inth'e-now preferred embodiment of the invention selected forillustration, and referring first to Figs. 1 to 5 inclusive, thereference character ll designates generally a swinging door, such as thedoor of a cabinet of the type known as a relay cabinet, being one of aseries installed along the right-of-way' of a railroad, the door framebeing designated generally as l2, while [3 designates an inner panel,adapted to. be engagedv with a rabbetedportion I4 of the: upright freeedgeofthedoor,.which it is desired to bring into firm, snug'contacttherewith.

In pursuance of the invention, 1. provide a hasp lock fasteningcomprising a hasp-element 15 mounted pivotally near the upright edge ofthe door, and carriedv bodily by the door, being also adapted. to swingabout its pivot into juxtaposition with a keeper element I6- when thedoor is.

closed.

The hasp element: includes amounting plate or. member. I! of. asize and:shape suitableto fitwithin a yoke l8 formed at the pivot end of thehasp' member, this mounting. plate being; secured to the door by aboltlfltransfixing the door and mounting. plate, the latter having anopening. 2!}v throughv which the: bolt passes, and wings 21 so" spacedas to accommodate the squared head 22 of the bolt, preventing it frombeing'turned from the outside of thedoor. The inside" end of the bolt 23is provided with theusual nut and washer securement.

The outer faces of the wings and adjoining part of the mounting plate l1are shown as provided with open sockets 24- to receive the pivot posts25- with which theJyoke: l 8is furnished, and spurs" 26: may be providedto prevent turning movements of the mounting plate, so that: when thehasp member i5 is swung out of engagement with the keeper [6 it: will:be maintainediin its horizontal plane.

The shank ii! ofthe hasp member may desirably be trough-shaped in.cross-section for the sake of strength with lightnessandat'itsfree endthe hasp has a head. 28 in. which is. fitted=a setscrew'29which isprovided witha part 30'designedi to serve as means'to permit the screwto be operated readily by hand, f-or lockingpurposes.

In the form of construction shown in Figs. 1 to 4 inclusive, the manual:operating means takes the: form'sof a wing-nut, fixed by a pin 3| to theshank of set-screw 29, and either'wing, or both wings. 32' of this nutmay be desirably pierced, as at 33, to receivetheloop 3'4 ofaconventional pad lock 35.

When the padlock is in. place,.its loop 34 hangsbetween the flanges 36at each sideof thetrou'gh shaped portion 21 of the hasp member, so thatthe wing nut cannot be turned until an operator provided with a keyopens and removes the lock 35.

The keeper element I6 is of improved construction especially designed tocooperate efliciently with the hasp element, to hold the latter in itsadjusted position securing the door H snugly against the frame membersl2 and I3.

5 For this purpose, the keeper element has a ridge 3! around the seat 38against which the nose of the set-screw 29 bears, and this ridgeprevents any chance of a. lateral escape by slipping of the set screwwhen the latter has been firmly driven in home.

The preferred shape and extent of this ridge 3'! is best shown in Fig.4, from which it will be clear that the part 3'! constitutes asubstantial barrier against the introduction of a tool, such as ascrew-driver, in an effort to reach and displace the set screw 29.

Such tampering is further prevented by a high wall part 39 ofsemicircular contour, reinforced at its rear by a buttress 40. Thekeeper also is made with a stout L-shaped base having a lug 4| securedto the door-jamb l2 by screw 42 which is protected by the hasp member 21from being withdrawn when the door is closed; and the base plate lug 43may be desirably secured firmly to a 25 square headed wood screw 44, orother suitable securement, according to the character of the cabinet towhich the device is applied.

It will be readily understood from the foregoing disclosure that thehasp-lock-fastening 'device is very strong, sturdy, economical tomanufacture and to install; cannot be readily removed, and is proofagainst tampering unless the latter be studied and carried to adestructive extent, and even such malicious interference will be atleast discouraged if not prevented to a large extent.

The same is true of the modification illustrated in Fig. 6, which ismerely illustrative of a considerable range of diverse forms in whichthe into vention may be embodied by those skilled in the art, upon thebasis of the disclosure found herein.

Fig. 6 shows a set screw which has a noncircular head 45 adapted toreceive a removable operating key 47 in place of the wing nut 30 shown45 in Fig. 1, but otherwise operating in the same manner.

It will be noted that the head of the hasp element is provided at 48with a protective wall which extends to a distance sufiioient to prevent50 easy operation of the set-screw 45 when the key 41 is not in place.This form of device is available for many applications of the devicewhere the risk of interference is less than warrants the provision of aconventional padlock, and in fact the form of lock shown in Fig. 6 maybe, and is, regarded as a padlock in the terminology of railroadequipment.

Although I have particularly described one particular physicalembodiment of my invention and explained the operation, construction andprinciple thereof, nevertheless, I desire to have it understood that theform selected is merely illustrative, but does not exhaust the possiblephysical embodiments of the idea of means underlying my invention.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is:
